Development and applications of the efficient hybrid RANS/ILES approach for the calculation of complex turbulent jets

Central Institute of Aviation Motors, State Scientific Center of Russian Federation, Moscow

Abstract: An efficient hybrid RANS/ILES approach is suggested for simultaneous calculation of flows in nozzles and jets of realistic configurations. The basic elements of the method are described, which permit of attaining a high accuracy of the results using relatively coarse grids. Results are given of calculations of the efflux of subsonic and supersonic jets from nozzles of different types. Good agreement between calculation results and experimental data is observed in the case of computational grids with $5.0 \times 10^51.2 \times 10^6$ nodes. The level of turbulence intensity is predicted both on the axis and in the layers of mixing of jets. The impact of parameters at the nozzle exit section on the characteristics of turbulence in the mixing layer in the initial region of jets is investigated.
